Hi Del How stupid of me. Found their web site in the meantime. Thanks Gerd

After a prolonged battle with my inner self, I visited the US website and placed an order for a few tanks. I was pleasantly surprised about the shipping costs to South Africa ( $ 25,-) which is reasonable for 3 tanks and considering there is no distribution near SA. Thanks and am looking forward to the the tank in the flesh.

Hi Steve Thanks a ton. It seemed such a good and practical product. I am not even sure they (USA) let me order from SA---will see.

Hi Del I am a little late but I did not use the forum for some time. I am very interested in a sound unit (I am looking at a Messerschmitt Bf109 from Hangar 9). Could you please let me have the e-mail address of the supplier ? I am living in SA and we sometimes have great difficulties with the sourcing of certain things. You guys up there are very lucky to have so many shops, dealers with all sorts of special things. Greetings Gerd Kopanski

Hi Everyone (sorry, not everyone-only those knowledgeable concerning my question) In the January 2013 issue there was an article from Brian Winch, which amongst others mentioned a type of fuel tank, called RotoFlow from an American company JLPRODUCTS. I also have mailed Brian for info. The tank is blow moulded with quite a clever brass clunk fixed within, so that the petrol supply never stops, irrespective of the plane's position during flight. The UK distributor was mentioned with a web site www.klasscote.co.uk It appears that the website is not functional anymore. Does anybody know what happened to this product or where in the UK it is available. I am living in South Africa and one of my daughters is living in London. My son from South Africa is going to visit middle of December and I had planned to mail-order 2 or 3 of these tanks to my daughter for my son to take back to SA. Your assistance would really be appreciated and I promise to put in a good word with Santa for you guys................................... Thanks Gerd Kopanski

Thanks, Now I got it ......................

Thanks Greybeard, so it is not a matter of HOW the motor is installed. Thrust Correction then is managed during flight . Correct /

Hi all the specialists What is meant by "checking" or "establishing" a thrust (line) , when installing/mounting the electric motor ? I was under the impression that the motor has to be mounted (on the firewall) absolutely true as per longitudeonal centre line of the plane and exactly 90 degrees square to this line. If there is indeed a different line (thrust line) and how does one know where this line is going to be without having flown the model ??? What about I.C. engines? This question arises as a result of many articles which cover assemblies of different planes from kits and referring to "....mounting a motor with a certain direction of thrust...." Or do I miss something here ???? Some aeronautical illumination would be thankful appreciated.

Thanks for all the input, which is mindboggling in diversity and opinions and convictions . It is - especially for an aeronautically or aerodynamically challenghed person - very difficult to differentiate between correct and incorrect . Initially, looking at all arguments, they somehow make sense (if one knows a little about physics) however I felt with some arguments that one or two hairs were split. I started off with the behaviour of a plane (trainer) on a simulator (Phoenix) and there I did not experience any difficulties with very slight rudder nudges 3 or 4 feet above ground while landing. I also must say that over time using the simulator I found it better to approach landing with a "very little" throttle up to 2 or 3 feet above ground because it gave me better response of the rudder, then throttle back to idle and then start flairing just before touch down. This worked for me (and the simulator) beautifully so far but then it remains to be seen whether it will work similarely in reality as well. Gerd

It seems that with my original "stupid" question I have opened a large bag of differing opinions . Good so because one can only take note and learn. Gerd

My Futaba is a FHSS type. Anyhow , I am bound to Futaba with respect to receivers. Not really a train smash..

JEEEWIZ I got something right !! If you are 5 or 10 m from the ground and throttled back it is suicide (except for a test pilot) to use ailerons - one little excitement too much and the plane had it (and your wallet too ....) Gerd

Hi John Thanks a ton for the MUD and the welcome. I cvome from an engineering background - but automotive - and the only thing concerning AIR there is the airfilter..................................... You understand I hope. Your explanations actually confirm my initial "suspicions" about ailerons and rudder. It came about because on landing approaches at lower altidudes I like to use the rudder for small directional changes . Gerd

I am new to model flying and currently I am quite proficient on the Phoenix simulator and I hope to do my maiden (with an instructor) at a local club-of course I am residing in South Africa so you cannot watch !!! Stupid questions: If I operate the ailerons on Phoenix and let the stick return to central, the plane carries on with the banking curve (is this normal ?) and only flies straight again after using opposite aileron. If I operate the rudder and let the stick return to centre the plane levels out again and flies straight. Is this the normal behaviour (ailerons) of model planes or should something be changed in the program ?? Thanks for the forthcoming aeronautical illuminations.

Hi FB Thanks, I feel much better know about the Magnums.
